If you've already read out the codes and have determined that the TCS module connections are your problem, then you can find the TCS module mounted to the bulkhead behind the drivers seat. You have to remove the top trim piece that goes from one side of the car to the other. The TCS module has 3 different connectors, each with 12 to 20 wires, some of which come from or go to the ECU. The reason I know all this is that I'm currently experiencing a transient 3-1 code. On startup, the ECU 'checks' some of the TCS interface signals and if it doesn't like what it sees, you can get a TCS warning light followed by a CEL.
